Choosing and using sun protection products

Look at the SPF Sunscreen products contain active ingredients that absorb into your skin to provide sun protection within the skin layers. The Sun Protection Factor (SPF) number on the product label tells you how long the product will protect your skin from burning UVB rays. Use a sunscreen with a SPF of 30 or higher.

Use products that contain one of the following to get broad spectrum protection:

zinc oxide

titanium dioxide

avobenzone

mexoryl
